` Cleaners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in y brushingand scrubbing and more particularly to bag cleaners.

The object of the invention is to provide a simple and efficient cleaning apparatus for bags made of fabric or textile material after the same have been used in order to clean them for relling and subsequent use. For example, in the use of bags for cement a great deal of the material Works into the fabric of the bag and remains there after the bag has been emptied and laidaside. This is also true of flour and `it is desirable to remove this material from the empty bag in order to have a practically clean bag for refilling and at the same time not to mutilate the bag during the cleaning` operation.

With the above and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

Tn the accompanying drawings Figure 1 represents a side elevation partly in section of this improved vbag cleaning apparatus; Fig. 2 represents a similar view taken in a plane at right angles to Fig. 1; Fig. 3 is a top plan view thereof; Fig. 4 is a transverse section taken on the line 4-4 of Fig. 2.

In the embodiment illustrated, a supporting frame 1 is shown in which a horizontally disposed driving shaft 2 is mounted, power for which may be supplied lfrom any suitable source, a driving pulley Sgbeing here shown adapted for connection with the source of power. A fan 4 is mounted on this shaft 2 and is adapted to be driven thereby and is surrounded by a suitable casing 5 from which an air pipe 6 to be described leads. An upright shaft 7 is also mounted in the frame 1 in a plane at right angles to the shaft 2 and is provided on its lower end with a beveled gear 8 which meshes with a similar gear 9 on the shaft 2 whereby rotary motion is imparted to the shaft 7 from the shaft 2 for a purpose to `be described. The shaft 7 constitutes the axle of a revoluble spiral brush 10 the bristles 10 of which are so arranged as to conduct the sacks fed into the top of the apparatus downward. This rotary brush is inclosed bypa foraminous cylinder 11 preferably constructed of woven wire but it may be of any other suitable or desired material. This cylinder is shown composed of a screen disk-like bottom 12'and an annular head 13 which are connected at intervals by bars 14 and around these bars 14 is arranged the foraminous covering of the cylinder. A brace ring 15 encircles the bars intermediately of their ends preferably midway thereof to prevent bulging of the cylinder.` The bars 14 are designed in addition to forming iongitudinal bracing elements or supports for the cylinder 11 to constitute scrubbing elements between which and the bristles 10 of the brush 10 the bags are designed to pass whereby they are thoroughly cleansed of the material impregnating them. i

The air discharge pipe 6 which leads from the casing 5 of the fan 4 is here shown ex-` tended horizontally below the cylinder 11 and provided with a plurality of upwardly extending discharge nozzles 16. Said pipe 6 is then extended upwardly into upright position substantially the full length of said cylinder and is provided with a plurality of longitudinally spaced' laterally extending discharge nozzles 16 arranged on its inner face opposite the cylinder l1. These nozzles 16 and 16 are designed to discharge air under pressure into the cylinder through the foraminous covering and bottom thereof to assist the bristles and scrubbing boards in `their cleansing action. This cylinder 11 is provided at its lower end with a discharge spout or outlet 17 through which the cleansed bags are adapted to be discharged onto a suitable conveyer 18 which carries them to a suitable place of deposit. Disposed adjacent the cylinder 11 is an endless conveyer 19 mounted on suitable pulleys 2O and 21 suitably supported above and below the ends of the cylinder l1. The pulley 2O is here shown mounted on the driving shaft 2 from which it receives its motion for drivingthe conveyer. This conveyer is provided with a plurality of longitudinally spaced flights 22 which are adapted to en- `The pulley 2O is disposed in a hopper 24:

in which the bags to be cleaned are disposed and the turning of the pulley and consequent turning of the belt 19 lifts by means of the iights 22, the bags upwardly and after theyare discharged through the spout or chute 23 they are carried downwardly by the spiral biz-ish 10 and thoroughly cleansed by the'brusliing and scrubbing action exertedthereon by the bristles 10 of said brush and the bars 14:.

The bristles l0 of the brush l0 are here shown of equal length and are constructed most effective action on the bags to be cleaned-it being understood that these bags are yfirst preferably turned before being fed s to the cylinder.

The conveyer 18which conducts the discharged cleaned bags to a point of deposit may be driven by any suitable means but is here shown driven bypulleys which receive their power from the driving shaft 2.

I claim as my invention vl. A sack cleaner comprising an upright foraminous cylinder, a 4 brush revolubly mounted in said cylinder, means arranged oppositefsaid cylinder for discharging air under pressurethereinto, andmeans for rotating said brush.

2. A l,sack cleaner. comprising .a foraminous .,cylinder, a revolubly inounted spiral brush disposed in said cylinder, means for revolving said brush, means for discharging the article to be cleaned in to the topofsaid cylinder, and an air discharge pipe extending longitudinally outside said cylinder andl provided with a plurality of discharge nozzles opening onto the cylinder.

3..A sack cleaner comprising a foraminous cylinder, a spiral brush mounted in said cylinder, scrubbing elements positioned in said cylinder for coaction with said spiral brush, means forfeeding the articles to be cleanedinto the top of said cylinder, a pipe arranged longitudinally of said cylinder on the outside thereof and provided with a plurality of nozzles discharging onto said cylsaid driving shaft, a brush mounted on saidv upright shaft, a cylinder encircling said brush and comprising a reticulated bottom and an open top, a plurality of bars connecting said top and bottom, a foraminous cover secured to the outer faces of said bars, a lQbracing element encircling said bars intermediately of the lengthv thereof, and means for discharging air underpressure onto said zcylinder.

of any suitable `material forfexerting the 1 structure, an upright spiral brush mounted therein, means for revolving said brush, a foraminous cylinder encircling said brush :and including areticulated bottom and anv 5. A sack cleaner comprising asupporting annular top, spaced bars connecting said top `and bottom and having their inner faces constructed to form a scrubbing board, a foraminous covering encircling said bars,

`and a discharge spout at the lower end of lmeshing with each other, a spiral brush mounted on said upright shaft, a foraminous cylinder' encircling said brush, a pipe lconnected with said fan casing and disposed longitudinally of said cylinder on the outside thereofjand provided with a plurality of longitudinally spaced discharge nozzles.

positioned to discharge air onto said cylinder. y

In testimony whereof I have hereunto set my hand in presence of two subscribing witxiesses.
